My instruction manual says not to run the product at full throttle for the first 2 to 3 tanks of fuel mix. Why is this? This can cause internal engine damage. STIHL recommends that you do not run your engine at wide open throttle without a load.
Using a chainsaw at full throttle without bar oil will cause serious damage to the engine of your chainsaw. Just as we mentioned, there are two main reasons why a chainsaw is best run at full throttle. They include: Personal Safety.
If your chainsaw engine dies at full throttle, check the following parts: the carburetor, fuel lines, fuel filter, air filter, and muffler. Our repair guide can help you identify the right part to stop your chainsaw's engine from dying at full throttle.
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.
If your chainsaw still starts and then stops working, check the air filter. Clean or replace the air filter if it is dirty or damaged. Another reason that your chainsaw starts and then stops working could be that the spark arrestor is dirty or clogged. If this is the case, clean it with a wire brush.

It's not fun trying to handle timber with a chainsaw that won't idle. Using a chainsaw is dangerous enough without having to balance the throttle to stop it from stalling. So why won't your chainsaw idle? The two most common reasons a chainsaw won't idle are a blocked air filter and an idle screw out of adjustment.
If you notice that your chainsaw is having trouble idling and not starting up, it could be because there is a blockage in your air filter. If it becomes clogged, it will restrict the amount of air going into the engine, making the chainsaw start up and die after you have given it gas.
Your engine wears faster when you apply full/big throttle. It is not so bad if your engine is warmed up, and you are not driving like this all the time, this is why you have the rev range up to 6500. When your engine is fully warmed up you can use the high revs for overtaking and going uphill.
Let the saw run for a minute or so first. This will allow it to reach an ideal warm temperature for use. Then, hit the throttle once and release it to set your engine to low idle.
Yes, chainsaws can overheat but it shouldn't happen under normal conditions. If the engine is running too hard or if it doesn't get sufficient ventilation or lubrication it can quickly overheat, which can lead to malfunction.
A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn't get too dull. On average, a chainsaw blade will retain its sharpness for about 3 hours of actively cutting through wood.
Information we found online suggests that Stihl Pro Chainsaws have a run time of about 2,000 hours. That means the saw would last you for a minimum of 5.5 years before dying. Keep in mind this time is rated for professional chainsaws and not for regular homeowner saws.
If your chainsaw does not start, the fuel may be too hot. To prevent this from happening, always use fresh fuel and reduce your operating time when the weather is warm. If your chainsaw will not start, place it in a cool area away from sunlight for at least 20 minutes.
The fuel filter might be clogged. A clogged fuel filter is often caused by leaving old fuel in the chainsaw. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and cause the engine to stall.
The letters on the screws represent High (H), Low (L) and Idle (T). The H screw regulates the Air/Fuel mix during high RPMs, while the L Screw does the same during low RPMs. The T screw regulates how much fuel is sent to the carburettor while idling until the throttle is pressed.
Your chainsaw can also shut down when turned sideways due to leakage or because the fuel lines need to be reset. In this case, please contact your local authorised dealer.
They are typically labeled L (low speed jet), H (high speed jet), and I (idler jet). Your saw may be labeled differently (in the photos in the Gallery below, the idler jet is labeled “S”), but you'll have three screws that correspond to these descriptions.
